Abstract (en)

[origin: WO2021229164A1] The invention relates to a material comprising a transparent substrate coated with a stack comprising at least one silver-based functional metal layer and at least two dielectric coatings, each dielectric coating comprising at least one dielectric layer, so that each functional metal layer is placed between two dielectric coatings, characterized in that the dielectric coating located in contact with the substrate comprises an intermediate coating comprising two different layers containing silicon, the two layers containing silicon consist of different chemical elements or compounds of the same elements in different proportions.
